SCN4A PrEST Antigen

Protein function: Pore-forming subunit of a voltage-gated sodium channel complex through which Na(+) ions pass in accordance with their electrochemical gradient. Alternates between resting, activated and inactivated states (PubMed:12766226, PubMed:29992740, PubMed:30190309, PubMed:15318338, PubMed:16890191, PubMed:18690054, PubMed:17898326, PubMed:19347921, PubMed:25707578, PubMed:26700687). Required for normal muscle fiber excitability, normal muscle contraction and relaxation cycles, and constant muscle strength in the presence of fluctuating K(+) levels (PubMed:12766226, PubMed:15318338, PubMed:16890191, PubMed:19347921, PubMed:25707578, PubMed:26700687, PubMed:26659129). [The UniProt Consortium] Buffer: PBS and 1M Urea, pH 7.4.
